Sunglasses are stylish, practical accessories that both block the sun's rays and add flair to outfits. Unfortunately, even with scratch-resistant coatings, sunglass lenses can become scratched. These scratches not only affect the appearance of the sunglasses but they can also reduce clarity and vision. According to SunglassesUSA, plastic sunglasses offer "less scratch resistance" than glass, making them more prone to surface damage. While your best bet is to protect your plastic sunglasses by using a case, scratches can be reduced and even removed using any of several methods and some common household products.
Spread glass etching material onto the front and back surfaces of the lenses. This glass etching compound will dissolve any anti-scratch or antiglare coatings without penetrating the actual plastic lens. Allow the product to remain on the lenses for five minutes before rinsing completely.
Spray both sides of the lens with furniture polish and begin buffing the lens with the cloth. Furniture polish is a mild abrasive that will polish and blend out any shallow scratches in the plastic. Rinse and repeat, if necessary.
Pour a dime-sized amount of metal polish onto a clean cloth. Rub the polish into the plastic lens using small, circular motions. Keep blending and buffing until the scratches diminish. Rinse when complete.
Spread a pea-sized amount of Carnauba wax directly into any noticeable scratches in the plastic. Press the wax into the scratch to fill in the scratches and even out the surface of the lens. Buff to a smooth finish using an eyeglass chamois cloth.
Never use glass etching products on glass lenses.
